HVAC Maintenance

top notch all around.

Very responsive. Very happy with install and follow up afterwards.

I have been a customer of Corcoran and Harnist since 1999 and I couldn't be happier with them. They have always taken great care of my equipment and I trust them completely. This is the second time they replaced my heating and air conditioning equipment \- in my last home and now in my condo \- and they did a wonderful job both times. I would highly recommend them to anyone.

Excellent workmanship and courteous installers along with professional knowledge of our new system.

They were so excellent to work with\-\-not a single person who wasn't helpful without being patronizing!

Fast install date and excellent service people

They worked helping to ID the issues with the old unit, and guided us to choosing the right unit to ultimately replace the old one.

We keep them on speed dial, and they always help!

Great company, great technicians.

Fast! Just moved to the area, needed consultation on a new HVAC system, and Corcoran Harnist came out the same day I contacted them. They offered excellent solutions to my concerns and completed the installation the next day. Very happy with my new system!

Brian and the crew were beyond awesome and they're professionalism and top notch! Our salesman Ken was also top notch and very professional! Thanks for a great job and we are life long customers moving forward!

I had no air conditioning, and Tim and his team responded immediately with outstanding service and new unit installation. They recommended the Carrier Infinity 5 stage air conditioner \- I have never heard a unit so quiet and my house has NEVER been this comfortable. I would recommend Corcoran \& Harnist and Carrier to anyone that needs a recommendation! They are the best!

Corcoran \& Harnist company was very knowledgeable, clean, fast and professional. I could not have expected more.

Very professional

Great service

Always a pleasure to work with Corcoran \& Harnist. Honest and Friendly!!

Very professional, knowledgeable, prompt, and courteous. Great company, and employees. I would recommend to anyone with ANY HVAC needs or questions.

installed in two days.

I have been a customer for many years.

Very professional and efficient. I was able to openly talk to the installers about how the work was going.

Perfect job start to finish. Great work. Great price.

Our furnace went on on one of the coldest days of the year. They pulled techs off other jobs to make sure we had heat. Thanks

We have been using Corcoran for several years and always have good consistent service

As a satisfied previous customer, we only looked to Corcoran \& Harnist to replace our old system!

Our 25 yr old heat pump was dying in middle of cold weather. We called and Corcoran came out quickly.

We recently purchased a furnace from Corcoran and Harnist. The representative who showed us the various options knew his stuff and did not try to sell us more than we needed nor wanted. The installation itself was done in a professional way, with the three installers being knowledgeable, cooperative with each other, and respectful of us. They left our house clean upon finishing the job and pointed out a scratch that they had left on the floor. The company quickly rectified the situation and we received a check to cover the repair. I would recommend them to anyone.

Excellent and dependable company in all regards for 30 years.

Full house replacement!
